Night started with cirrus in all parts of the sky but cleared around 2:00UT (?). Seeing was very good for most of the night, (0.75-1.0"). Poor tracking/guiding to the north didn’t allow many or our remaining proposals to take advantage. Lost internet at ~6:30UT ARGH! (Detailed notes on those pages. Luckily few problems.) The DES folks had problems at the beginning of the night with images in poor focus because the filter LUT was not functioning at this time. Ann fixed this after they noticed, and we had no problems during our time. Minor SISPI problems. We once had to hit the "Reset" button in order to get the Interlock and OCS to come back up again. We lost an exposure from the queue, and two exposures were automatically entered in the queue to compensate for this, when only one was needed.
